Filter by:This study will evaluate the effectiveness of directly observed therapy plus antidepressant medication in improving adherence to antiretroviral drug therapy among HIV-infected homeless and marginally housed people with depression.
The study aims to ascertain whether the sole replacement of tenofovir with abacavir once a day improves the immunological response obtained with tenofovir + ddI or whether it is better to perform a double replacement of tenofovir and ddI with abacavir + lamivudine (joint formulation) in a single daily dose to achieve these objectives.
This study will evaluate the signs and symptoms associated with Fuzeon injection (90mg sc) using the B2000 needle-free injection device, in HIV-1 positive patients experienced to Fuzeon treatment, but having difficulty tolerating long-term (>4 weeks) administration of Fuzeon with the standard needle and syringe. Patients will be randomized to the B2000 device or the standard needle and syringe for 4 weeks; all patients will use the B2000 device for the next 4 weeks. The anticipated time on study treatment is <3 months, and the target sample size is 100-500 individuals.
The main purpose is to explore whether atazanavir/ritonavir (ATV/RTV) single enhanced protease inhibitor therapy can maintain virologic suppression without a marked increase in virologic failure.
We hypothesize that a simple bridging ARV regimen that tends to select for virus with a low replicative capacity may tend to stabilize CD4 cell counts and HIV viral load and might be an option to consider in patients with MDR HIV. This strategy will provide them with the bridge they desperately need so that they can await the development of new therapies that when used in combination will give them the best chance in achieving complete virologic suppression.
The study aims to evaluate the changes in mitochondrial DNA (mDNA) by means of the mDNA/nuclearDNA (nDNA) ratio as a marker of mitochondrial toxicity following the interruption of nucleoside analogues.
In treatment naïve HIV infected subjects, combination antiretroviral therapy including efavirenz combined with tenofovir and emtricitabine will offer non-inferior antiretroviral efficacy over 48 weeks, compared to either atazanavir boosted with ritonavir combined with tenofovir and emtricitabine or tenofovir and emtricitabine combined with zidovudine and abacavir, as assessed by change from baseline plasma HIV-1 RNA viral load.
The purpose of this study is to confirm that apricitabine does not induce any clinically significant effect upon electrocardiogram (ECG) parameters at doses consistent with the maximum exposure expected to occur in clinical practice.
To study the pharmacokinetic properties, safety and viral resistance pattern of the combination of tenofovir disoproxil fumarate and emtricitabine in HIV-1-infected pregnant women and their newborns, with a view to prevention of mother-to-child transmission (PMTCT) of HIV-1 in Africa and Asia.
To further investigate differences in the immunologic function of various lymphocyte subsets in HIV-infected patients who are treated early in their infection and during the chronic phase of the infection. Studies will also be done to further delineate the various antigen-specific and innate immune responses including characterization of soluble factors associated with primary HIV infection.
